# Razer Key Light Chroma: a SignalRGB client for its lighting protocol

> Razer Key Light Chroma adds local RGB control to SignalRGB using the lamp's documented TCP and UDP message sequence. It performs acknowledged setup on TCP port 10003, streams 95-byte color packets on UDP port 10005, and includes fixtures and tests comparing packets with the original SDK.
